Blood flow and blood volume within recurrent tumour tissue are also reported to be elevated in comparison with therapy-altered tissue with corresponding decreases in transit time.
Since the small intestine is the major site for absorption of many compounds, reduction in transit time will decrease the time available for absorption for many of the poorly soluble and slowly dissolving drug compounds such as ranitidine.
Decrease in intestinal transit time by morphine and atropine are linked to delay in gastric emptying [ 66- 69].
Probably extract increased the reabsorption of water thereby decreasing intestinal motility as observed by the decrease in intestinal transit of charcoal meal.
During the downstream cycle, the sound wave travels with the flow of blood, which results in a decrease in total transit time for the same flow amount.
There was an associated decrease in mean transit time and no change in relative cerebral blood volume, suggesting a vasogenic process.
The extract (1000 mg/kg) produced a decrease in intestinal transit comparable to atropine (5mg/kg), and significantly (p<0.01) inhibited castor oil-induced enteropooling.
An increase in faecal wet and dry weight is observed when the diet comprises unsaturated carbohydrates [ 10] and the consequent decrease in the transit time in the intestine has an influence on the level of absorbed skatole [ 11].
Decrease in intestinal transit induce by the extract could have lead to an increase of enteroinvasive infections, but this might have been prevented by the antimicrobial properties of the extract.
Furthermore, the decrease in intestinal transit time, prolonging the action of the Beta-Galactosidase in the intestinal lumen, decreases, in turn, the osmotic load of the lactose which, as a nonabsorbable sugar, could accelerate the intestinal transit time reducing the time available for lactose hydrolysis [ 30– 30].
